Add recorded sound to anything - Change sound from toys n gadgets

Want to add sound or voice recordings to projects, cards, gifts, toys and more? Perhaps you'd like to change the sounds that come out of these types of things. This video is for you! I will walk through the process of how to record and use a simple, low cost device that can be used inside of so many projects. There are options to control playback from buttons, light and more too! Use your voice, sound files and other recordings.

In past videos I have shown what is inside toys and gadgets that use sound recordings. I have even shown how to repair or repurpose many of these things. But one question I get asked allot is "can I change the sounds that are being played back?" This video will show what I do to make that happen. This is perfect for gifts, holiday decorations (especially Halloween), toys and pranks.

I'll be making a toy dinosaur go instead of roar for a birthday present.

Imma make my woody toy say “I put the new forgis on the jeep”

[Cartooncatali]

Doing this to a popular toy then returning it to be put back on the shelf after changing its phrases would be fun lol

Awesome video! One of the more helpful ones out there! Thanks a lot 👌

I've come up with a theoretical question on the possibility of using a computer to record a sound on the ISD 1820.
1. Desolder and remove the microphone
2. Strip the ends of a 3.5mm jack
3. Solder the wires to the circuit board where the mic was
4. Plug 3.5mm jack into audio jack on computer
5. Press record on chip and play sound through computer

In theory, this would allow the chip to record the signal being transmitted through the 3.5mm jack! But I've also thought of counterarguments, haha:

• The 3.5mm jack is line-level. The ISD 1820 is expecting a mic-level signal to send to the "on-chip preamp" (according to a spec sheet). According to an article I googled, "connecting a line-level source […] to a mic-level input will cause the sound to be loud and distorted because the line signal is much stronger than what the mic input will accept". So that sucks.
But perhaps difference in voltage can be mitigated by attaching a resistor to the 3.5mm? Step it down from the 1.000V range to the .001V-.010V range... Ok, my brain is hurting, I'll think about this part later.

• I don't even know if the signals are compatible. I mean, I think they're both analog, and they obviously both involve sound frequencies, but what do I know?

• All the 3.5mm cables I have lying around are stereo, so I would only be able to attach one channel to the circuit. I think this is inconsequential, though.



If anyone is still reading this comment, tell me your thoughts! I'll probably be experimenting with this in the near future :)

Thank you so much for providing such clear and easy to follow instructions. I've been trying to figure this out for a long time

[truthseeker]

First of all i want to appreciate you that you are trying to give answers to the questions on almost every question in the comment box, while other youtubers hardly do that.(sorry for my bad english). Sir, i m a house wife and doesn't have enough technical knowledge, but i really really want to make my own customized soft doll for my toddler.can you please guide me in some details about what things i have needed to make a doll which have inbuilt buttons in her both palms and in both the feets and when pressed any of button, a prerecorded audio plays.for example, when we press its right palm, a morning time routine audio plays, when left palm press, a lullaaby plays, when we touch or press its right feet, a bed time routine audio plays, etc. I will highly appreciate you if you guide me in this project. Kindly reply back sir, I m impatiently waiting for your reply.Thank You !

That was pretty informative. Thank guy

I am going to have so much fun with this

[angelcenteno]

I’m gonna make South Park’s “stop touching me Elmo” for my friend. he loves South Park.

Hi great video, would you be able to recommend a sound board that would have a enough memory to play several hours of auto at good quality. I would also need to include buttons with functions such as play/stop, next, previous almost like an mp3 player. Thanks.

[faezfadzli]

Awesome vid. Can i know how to make the sound play right after the power supply goes in without push any button.

[syedibrahim]

Awesome Video and exactly what i was searching for. May i know if there is anyway i can have a higher volume output from the speakers?

[whelfshoe]

I understand if you're not able to answer this but I do have an inquiry.

I have a toy that moves, and I'm not able to replace the sound that's on the board inside it. I'm assuming that if I remove the speaker from the original board that will eliminate the problem of the original sound playing. So if I did that, and added as well a new board with a new sound, would there be a way for me to wire the new board up to the same button, so that the button both triggers the sound from the new board and the movement from the old board? I hope this makes sense >- <

[trebory]

Wow! This is EXACTLY what I've been looking for all day. Question about using different speakers though, is there anything that needs to be thought about when getting a higher quality speaker?

Like do you need to alter the voltage, and is there a certain type of speaker I should look for that can give me a decent range as far as playback?

Also, I know you showed using an upgraded power source and speaker with the ISD1820, but what about upgrading one of the ones that you can directly upload your own sounds to?

Thanks!

Amazing video. Thank for sharing so much. And I have a question could you please tell me what happen if I want to add sound into a book, and when I open each page, the different sound can be turned on automatically ? And when I close to open next page, the old sound will be turned off and the new sound of the next page will be turned on?

[claudettealexander]

Really useful information for me into creating my own stuff

[critzbigdmg]

Would use this to replace the Christmas songs on a singing Santa with like a Cannibal Corpse song just for the laughs.

[marvelmaniac]

Hi! Great and informative video! Can you share which voice recording sound playback module incorporates voice activation by keyword?

[chickenandironbrotherteamwork]

I am making a Buzz Lightyear voice box and a woody voice box

[MrHexxed]

Looking to add a sound file to a lightgun build. Out of all the sound recorders you tested, which one did you find had the fastest start to play once pushing the play button? The lag of some of these is unusable in this particular instance but I'm sure there's something out there that would work. Thanks!
